The whole reason the Irish subsisted on potatoes was that the corned beef they were wage slave raising and producing was to be eaten only by English and French folks that could afford the extravagant costs. Another type of corned beef was here already in the US. It was the Jewish kosher corned beef that became synonymous with Irish American culture.
